Week 11 of the NFL season is here, and Cortana is back to make picks in a head-to-head showdown with Elo.

We looked at two popular systems used to pick NFL games: Cortana, Microsoft's digital assistant, and Elo, the modeling system used by Nate Silver's data-journalism site, FiveThirtyEight.

In both cases, the computers are picking outright winners and not against the spread. However, each gives a likelihood that a team will win — which, in theory, could help measure the strength of certain lines.

Cortana is off to a strong start this season, correctly picking 67% of the games overall. Elo has nailed 62% overall. Both models have cooled recently, going just 16-11 over the last two weeks.

Here are the picks for Week 11, with each team's percent chance of winning in parentheses. Point spreads are for reference, via Vegas Insider as of Thursday morning.
